Tamped Gravel Path Base
Building a gravel path in compacted layers — a tamped crushed-stone base under tamped decorative gravel — so it stays firm underfoot and gives weeds nowhere to root.
Lock Loose Pea Gravel Into Place With a Spray-On Binder
Pea gravel migrates out of beds and paths because nothing holds the stones to each other. A clear spray-applied binder soaks in and glues them into a permeable crust that still drains but stops scattering.

The Problem
Pea gravel is rounded rather than crushed, so the stones roll past each other instead of locking together. A path spreads into the lawn, a bed migrates onto the patio, and the low spots need topping up every year or two.
Edging holds the perimeter and does nothing about the surface. Angular gravel like crushed granite knits together and stays, but it's a different look and a different feel to walk on.
The Technique
A gravel binder is a liquid adhesive — polyurethane or acrylic depending on the product — applied over laid gravel. It runs down between the stones, sets at the contact points, and leaves the surface permeable so water still drains through.
- Lay and level the gravel as normal, and let it dry out.
- Clear leaves and debris off the surface. Anything on the stones when the binder goes on gets glued in.
- Apply the binder evenly across the surface, working in manageable sections so nothing skins over before the next pass.
- Leave it to cure before walking on it.
The result holds together under foot traffic and a leaf blower but drains like loose gravel.
What the Video Doesn't Tell You
Worth establishing from the product datasheet before buying, because it varies between brands and the source doesn't cover any of it: the coverage rate per litre, whether the manufacturer intends full-surface treatment or only the edges and high-traffic strips, the cure time, and the freeze-thaw rating. That last one decides whether the crust survives a winter or breaks up into plates.
Pro tip: Bound gravel is much harder to add to later, because fresh stones sit on the crust rather than bedding into it. Get the depth right and the surface where you want it before any binder goes down.
Safety note: These are solvent or resin based. Work in the open, keep it off adjacent paving and plants — it bonds to those as readily as to gravel — and follow the product's own protective equipment guidance rather than assuming a garden product is benign.
